Description

Technical Field

[0001] This invention belongs to the field of facial mask processing technology, specifically a device for applying release paper to facial masks. Background Technology

[0002] With the improvement of people's living standards and the continuous growth of demand for beauty and skin care, facial masks, as a convenient and effective skin care product, have seen a continuous increase in market demand. As a result, the facial mask processing industry has also developed rapidly, constantly pursuing higher production efficiency and better product quality to meet the diversified needs of the market. In the production and processing of facial masks, the lamination process using a lamination device is a crucial step. Currently, the most common lamination devices on the market mainly use fixed extrusion rollers to achieve the lamination operation. The basic working principle is to feed the facial mask substrate and the release paper to the extrusion rollers respectively. The extrusion rollers, which are pre-set with a fixed pressure, squeeze the facial mask and the release paper to make them fit tightly together, thereby completing the lamination work.

[0003] In actual production, the surface of the mask often exhibits a certain degree of unevenness, such as bumps or depressions. When bumps appear on the mask surface, the fixed extrusion roller will encounter greater resistance at the bumps. This not only increases the operating load of the equipment and leads to increased energy consumption, but may also cause excessive extrusion of the bumps, resulting in damage to the mask substrate or deformation of the release liner, affecting the lamination quality. Conversely, at the depressions on the mask surface, the pressure of the fixed extrusion roller is relatively insufficient, making it impossible for the release liner to fully adhere to the mask substrate, which can easily generate air bubbles or gaps, resulting in weak lamination and reduced product sealing and stability.

[0004] Therefore, the present invention provides a device for coating release paper for mask processing. Summary of the Invention

[0008] Preferably, the elastic support assembly includes a feed box located on the side of the receiving plate away from the support frame. Arc-shaped sliding shafts are fixedly installed at the top and bottom of the feed box. The outer walls of the arc-shaped sliding shafts are slidably connected to the inner walls of the receiving plate. Sliding plates are slidably installed on the outer walls of the arc-shaped sliding shafts. An elastic element A is fixedly installed between the sliding plate and the receiving plate. The elastic element A is sleeved on the outer side of the arc-shaped sliding shaft. The sliding plates all abut against the feed box.

[0009] Preferably, two adjusting plates are rotatably mounted on the outer wall of one of the rotating shafts, and connecting plates are fixedly mounted on the outer walls of the sliding plates. The two connecting plates are respectively fixedly connected to the two adjusting plates, and the inner wall of the feed box is provided with an adjusting assembly.

[0010] Preferably, the adjusting assembly includes an adjusting screw, which is threaded onto the inner wall of the feed box. A pressing block is rotatably mounted on one end of the adjusting screw, and the adjusting plates all abut against the pressing block. An adjusting knob is fixedly mounted on the end of the adjusting screw away from the pressing block.

[0011] Preferably, the outer wall of the feed box is symmetrically fixedly equipped with sliders, the inner wall of the machine body is symmetrically provided with sliding grooves, the inner wall of the sliding grooves is slidably connected to the outer wall of the sliders, the positioning blocks are slidably installed on the inner wall of the sliding grooves, and a drive assembly is provided on one side of the feed box.

[0012] Preferably, the drive assembly includes a horizontal plate, which is fixedly installed on the inner side of the machine body. A telescopic cylinder and a stabilizing frame are fixedly installed on the outer wall of the horizontal plate. The inner wall of the stabilizing frame is fixedly connected to the outer wall of the telescopic cylinder. A force-bearing block is fixedly installed on the top of the feed box, and the force-bearing block is fixedly connected to one end of the telescopic cylinder.

[0013] Preferably, a take-up roller is rotatably mounted on the inner wall of the machine body, and a drive motor is fixedly mounted on the outer wall of the machine body, with the output end of the drive motor fixedly connected to one end of the take-up roller.

[0014] Preferably, two sets of connecting frames are fixedly installed on the outer wall of the feed box, and guide rollers are symmetrically rotatably installed between the inner walls of each set of connecting frames.

[0015] Preferably, a dynamic friction plate is fixedly installed on the outer wall of the take-up roller, a hinge seat is fixedly installed on the bottom of the inner wall of the machine body, a rotating plate is rotatably installed on the inner wall of the hinge seat, a fixed friction plate is fixedly installed on one end of the rotating plate, an elastic element B and a telescopic rod are fixedly installed between the rotating plate and the hinge seat, the elastic element B is sleeved on the outside of the telescopic rod, and a pressing rod is fixedly installed at the bottom of the feed box, the pressing rod abutting against the rotating plate.

[0016] The beneficial effects of this invention are as follows: 1. The mask processing release paper laminating device of the present invention provides elastic buffering and automatic adjustment capabilities for two extrusion rollers through an elastic bonding component. When the extrusion rollers are subjected to resistance from the mask and release paper, the elastic bonding component deforms according to the force. When a protrusion appears on the surface of the mask, the protrusion will exert an upward force on the extrusion rollers, and the two extrusion rollers will open under the action of the elastic bonding component. The elastic deformation of the elastic bonding component can buffer part of the force, avoid the extrusion rollers from being subjected to excessive rigid resistance at the protrusion, and reduce the risk of damage to the mask substrate and deformation of the release paper. When a depression appears on the surface of the mask, the elastic force of the elastic bonding component will cause the extrusion rollers to apply relatively large pressure to the depression, making up for the problem of insufficient pressure of the extrusion rollers. Thus, the extrusion rollers can automatically adjust the pressure according to the undulation of the mask surface, reduce the pressure difference at different positions, and improve the uniformity of lamination.

[0017] 2. The mask processing release paper coating device of the present invention can make two adjusting plates rotate synchronously in opposite directions through the adjusting component. When the adjusting plate rotates, it will drive the connecting plate to rotate. When the connecting plate rotates, it will force the sliding plate to slide along the arc-shaped sliding shaft, compressing or releasing the elastic element A, thereby changing the preload of the elastic element A. The preload of the elastic element A directly determines the initial elastic force of the receiving plate on the support frame. Then, the mutual contact force of the extrusion rollers is adjusted through the lever principle, so that the pressure applied to the mask by the two extrusion rollers is changed, thereby enabling the device to adapt to the production needs of different masks.

[0018] 3. The mask processing release paper laminating device of the present invention adopts a step-by-step conveying of the mask. After each section is conveyed, the drive component causes the extrusion roller to roll in the opposite direction from the side of the mask movement direction. This design allows the extrusion roller to roll and squeeze the mask in the opposite direction during the short time when the mask is stopped from being conveyed. By using the reverse friction and pressure, air bubbles that may exist between the mask paper and the release paper are squeezed out and eliminated, effectively solving the problem of air bubbles easily generated during the laminating process of existing devices, and further improving the tightness and quality of the lamination.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6As shown in the embodiment of the present invention, a mask processing release paper laminating device includes a body 1. A mask roller 2 is rotatably mounted on the inner wall of the body 1. A release paper roller 3 is rotatably mounted on the inner wall of the body 1 below the mask roller 2. A bonding roller 4 is rotatably mounted on the inner wall of the body 1 above one side of the mask roller 2. An elastic extrusion assembly is provided on the inner side of the body 1. The elastic extrusion assembly includes two extrusion rollers 5, which are located on the side of the bonding roller 4 away from the mask roller 2. During the laminating process, the mask paper and the release paper are pulled out from the mask roller 2 and the release paper roller 3, respectively. The pulled-out mask paper and the release paper pass through the bonding roller 4 and the elastic extrusion assembly in sequence. When the mask paper and the release paper pass through the bonding roller 4, the bonding roller 4 will cause the mask paper and the release paper to be initially bonded. After the initial bonding is completed, when the mask paper and the release paper pass through the elastic extrusion assembly, the mask paper and the release paper will pass between the two extrusion rollers 5. When the two extrusion rollers 5 are in contact, the elastic bonding assembly keeps them in a state of mutual compression. The elastic bonding assembly provides elastic buffering and automatic adjustment capabilities for the two extrusion rollers 5. When the extrusion rollers 5 are subjected to resistance from the face film and release paper, the elastic bonding assembly deforms according to the force. When a protrusion appears on the face film surface, the protrusion will exert an upward force on the extrusion rollers 5, and the two extrusion rollers 5 will open under the action of the elastic bonding assembly. The elastic deformation of the elastic bonding assembly can buffer part of the force, avoid the extrusion rollers 5 from being subjected to excessive rigid resistance at the protrusion, and reduce the risk of damage to the face film substrate and deformation of the release paper. When a depression appears on the face film surface, the elastic force of the elastic bonding assembly will cause the extrusion rollers 5 to apply relatively large pressure to the depression, making up for the problem of insufficient pressure of the extrusion rollers 5. Thus, the extrusion rollers 5 can automatically adjust the pressure according to the undulation of the face film surface, reduce the pressure difference at different positions, and improve the uniformity of film coating.

[0023] like Figures 1 to 6As shown, the elastic extrusion assembly also includes positioning blocks 6 and elastic support components. There are two positioning blocks 6 located inside the machine body 1. A rotating shaft 7 is fixedly installed on the inner wall of each positioning block 6. Two support frames 8 are rotatably installed on the outer wall of each rotating shaft 7. The two support frames 8 form a group. Extrusion rollers 5 are rotatably installed on the inner walls of the two groups of support frames 8 respectively. A receiving plate 9 is fixedly installed between each group of support frames 8. Extrusion rollers 5 and receiving plates 9 are fixedly installed at both ends of the two groups of support frames 8 respectively. The two receiving plates 9 are supported by the elastic support components. The support frame 8 is connected to the rotating shaft 7 to form a lever structure. When the mask sheet and the release paper enter between the two extrusion rollers 5, the elastic support component applies an elastic force to the support frame 8 through the receiving plate 9. The force is transmitted to the extrusion rollers 5 using the lever principle, keeping them in a state of mutual contact. When the mask is thick, the support frame 8 rotates around the rotating shaft 7, the elastic support component is compressed, and the pressure increases. When the mask is thin, the elastic support component returns to its original shape, and the pressure decreases, thus avoiding the situation where the pressure is too high and causes damage or insufficient pressure and cannot remove bubbles.

[0024] like Figures 1 to 6 As shown, the elastic support assembly includes a feed box 10, located on the side of the receiving plate 9 away from the support frame 8. Arc-shaped sliding shafts 11 are fixedly installed at the top and bottom of the feed box 10. The outer walls of the arc-shaped sliding shafts 11 are slidably connected to the inner walls of the receiving plate 9. Sliding plates 12 are slidably installed on the outer walls of the arc-shaped sliding shafts 11. Elastic elements A13 are fixedly installed between the sliding plates 12 and the receiving plate 9. The elastic elements A13 are sleeved on the outer side of the arc-shaped sliding shafts 11. The sliding plates 12 are all connected to the feed box 9. The material box 10 is in contact with the material box; a through groove is provided on the inner side of the material box 10 to provide conditions for the mask to pass through. The top and bottom of the material box 10 are fixed with arc-shaped sliding shafts 11. The receiving plate 9 can slide along the arc-shaped sliding shafts 11. An elastic element A13 is provided between the receiving plate 9 and the sliding plate 12. The elastic element A13 transmits the elastic force to the receiving plate 9 through the contact between the sliding plate 12 and the material box 10, and then converts it into the mutual contact force of the extrusion rollers 5 through the support frame 8 and the rotating shaft 7.

[0025] like Figure 7As shown, two adjusting plates 14 are rotatably mounted on the outer wall of one of the rotating shafts 7, and connecting plates 15 are fixedly mounted on the outer wall of each sliding plate 12. The two connecting plates 15 are fixedly connected to the two adjusting plates 14 respectively. An adjusting assembly is provided on the inner wall of the feed box 10. The adjusting assembly can make the two adjusting plates 14 rotate synchronously in opposite directions. When the adjusting plates 14 rotate, they will drive the connecting plates 15 to rotate. When the connecting plates 15 rotate, they will force the sliding plate 12 to slide along the arc-shaped sliding shaft 11, compressing or releasing the elastic element A13, thereby changing the preload of the elastic element A13. The preload of the elastic element A13 directly determines the initial elastic force of the receiving plate 9 on the support frame 8, and then adjusts the mutual contact force of the extrusion rollers 5 through the lever principle, so that the pressure applied to the face film by the two extrusion rollers 5 is changed, thereby enabling the device to adapt to the production needs of different face films.

[0026] like Figures 7 to 8 As shown, the adjustment assembly includes an adjustment screw 16, which is threaded onto the inner wall of the feed box 10. A pressing block 17 is rotatably mounted on one end of the adjustment screw 16, and the adjustment plates 14 all abut against the pressing block 17. An adjustment knob 18 is fixedly mounted on the end of the adjustment screw 16 away from the pressing block 17. When it is necessary to adjust the contact force between the two pressing rollers 5, the adjustment knob 18 is rotated. The adjustment knob 18 will drive the adjustment screw 16 to rotate. When the adjustment screw 16 rotates, it will drive the pressing block 17 to move through the threaded engagement with the feed box 10. When the pressing block 17 moves, it will press against the two adjustment plates 14. After being pressed, the two adjustment plates 14 will rotate synchronously, changing the angle between them, thereby changing the position of the sliding plate 12 on the arc-shaped sliding shaft 11, achieving the effect of adjusting the contact force of the pressing rollers 5.

[0027] like Figures 2 to 4As shown, sliders 19 are symmetrically fixedly installed on the outer wall of the feed box 10, and grooves 20 are symmetrically opened on the inner wall of the machine body 1. The inner walls of the grooves 20 are slidably connected to the outer walls of the sliders 19, and the positioning blocks 6 are slidably installed on the inner walls of the grooves 20. A drive assembly is provided on one side of the feed box 10. Through the cooperation of the sliders 19, the positioning blocks 6, and the grooves 20, the elastic extrusion assembly is made capable of sliding. During the lamination process, the mask paper and the release paper move in a step-by-step manner. Whenever the mask paper and the release paper move a certain distance, the drive assembly pushes the elastic extrusion assembly towards the mask paper. The film paper and the release paper move in opposite directions and then reset. The slider 19 and the positioning block 6 slide inside the chute 20. The mask is conveyed in a step-by-step manner. After conveying a section, the drive component makes the squeezing roller 5 roll in the opposite direction from the side of the mask movement direction. This design allows the squeezing roller 5 to roll and squeeze the mask in the opposite direction for a short period of time when the mask stops being conveyed. By using the reverse friction and pressure, air bubbles that may exist between the mask paper and the release paper are squeezed out and eliminated. This effectively solves the problem of air bubbles that are easy to be generated during the lamination process in existing devices, and further improves the tightness and quality of lamination.

[0028] like Figure 4 and Figure 6 As shown, the drive assembly includes a horizontal plate 21, which is fixedly installed on the inner side of the machine body 1. A telescopic cylinder 22 and a stabilizing frame 23 are fixedly installed on the outer wall of the horizontal plate 21. The inner wall of the stabilizing frame 23 is fixedly connected to the outer wall of the telescopic cylinder 22. A force-bearing block 34 is fixedly installed on the top of the feed box 10 and is fixedly connected to one end of the telescopic cylinder 22. The telescopic cylinder 22 is fixed to the inner side of the machine body 1 by the horizontal plate 21 and the stabilizing frame 23, providing a stable fulcrum for the telescopic cylinder 22. When the telescopic cylinder 22 extends or retracts, it pushes the force-bearing block 34 to move. When the force-bearing block 34 moves, it drives the feed box 10 to move, thereby moving the two extrusion rollers 5 and providing power for the operation of the device.

[0029] like Figures 1 to 3 As shown, a take-up roller 24 is rotatably mounted on the inner wall of the machine body 1, and a drive motor 25 is fixedly mounted on the outer wall of the machine body 1. The output end of the drive motor 25 is fixedly connected to one end of the take-up roller 24. One end of the mask paper and the release paper are fixed on the take-up roller 24. When the device is working, the drive motor 25 will drive the take-up roller 24 to rotate. When the take-up roller 24 rotates, it will drive the mask paper and the release paper to move, thereby providing power for the movement of the mask paper and the release paper.

[0030] like Figure 8As shown, two sets of connecting frames 26 are fixedly installed on the outer wall of the feed box 10. Guide rollers 27 are symmetrically rotated between the inner walls of each set of connecting frames 26. After the mask paper and the release paper are pasted together, they will pass through the inside of the feed box 10. The guide rollers 27 are set on both sides of the feed box 10 through the connecting frames 26. The guide rollers 27 guide the pasted mask and prevent the mask from scratching the feed box 10 during the conveying process.

[0031] like Figures 2 to 4 and Figure 9 As shown, a moving friction plate 28 is fixedly installed on the outer wall of the take-up roller 24, and a hinge seat 29 is fixedly installed on the bottom of the inner wall of the machine body 1. A rotating plate 30 is rotatably installed on the inner wall of the hinge seat 29, and a fixed friction plate 31 is fixedly installed on one end of the rotating plate 30. An elastic element B32 and a telescopic rod are fixedly installed between the rotating plate 30 and the hinge seat 29. The elastic element B32 is sleeved on the outside of the telescopic rod. A pressing rod 33 is fixedly installed at the bottom of the feed box 10, and the pressing rod 33 abuts against the rotating plate 30. When conveying the face film paper and the release paper, the fixed friction plate 31 and the moving friction plate 28 are in a separated state. Therefore, the drive motor 25 can drive the take-up roller 24 to rotate to realize the conveying work. When the telescopic cylinder 22 extends and drives the pressing roller 5 to move, the feed box 10 will drive the pressing rod 33 to move away from the rotating plate 30, and the rotating plate 30 will be at the elastic element B32. Under the action of the pressure roller 5, the fixed friction plate 31 and the moving friction plate 28 are brought into contact, thereby locking the take-up roller 24. It should be noted that a transmission assembly is provided between the mask roller 2, the release paper roller 3 and the take-up roller 24. The transmission assembly can be composed of a transmission belt and a transmission wheel, so that the mask roller 2, the release paper roller 3 and the take-up roller 24 rotate synchronously. Therefore, after the take-up roller 24 is locked, the mask roller 2 and the release paper roller 3 will also be locked. By locking the take-up roller 24, the mask roller 2 and the release paper roller 3, it is prevented that the extrusion roller 5 will pull the mask when it moves back and forth, causing the take-up roller 24, the mask roller 2 and the release paper roller 3 to rotate and causing the mask to loosen, which would affect the subsequent production quality. When the telescopic cylinder 22 retracts and the extrusion rod 33 is reset, the extrusion rod 33 will push the rotating plate 30 again to separate the fixed friction plate 31 and the moving friction plate 28, and the mask roller 2, the release paper roller 3 and the take-up roller 24 will resume rotation.
